The Science Behind a Simple White Powder
Sodium bicarbonate, commonly referred to as baking soda, is one of the most versatile and important chemicals in modern society. It can be used as a mild leavening agent in the kitchen, to be a crucial component in dialysis, water purification, the suppression of fires, and emissions control. This chemical has earned itself a secluded but important place in industry and daily life.
But behind the apparent simplicity is a complicated process of precise manufacturing, sustainability along with industrial foresight. There is no other company in India is more exemplary as Tata Chemicals.
Based in Mithapur, Gujarat, Tata Chemicals is not just the market leader in soda ash and sodium bicarbonate manufacturing in India, but also has expanded internationally with its premium quality and environmentally friendly bicarbonate products. Through the integration of technology with green chemistry, as well as brand-specificization, Tata has transformed a basic substance into a known product family, which includes Medikarb™ to treat pharmaceuticals, and EcoKarb® to help with environmentally-friendly applications.
Tata’s strategy isn’t confined within corporate walls. With the increasing demand and a wide range of technology available startups and entrepreneurs have a great opportunity to create the sodium bicarbonate manufacturing units and create successful companies around these units.
Tata Chemicals: Transforming Chemistry into Opportunity
The tale of Tata Chemicals’ success with sodium bicarbonate is closely tied to its control of the upstream flow of soda ash, as well as its long-standing quest for innovative business practices and ethical business practices.
Beginning from the Mithapur complex, Tata manufactures soda-ash by the Solvay process that utilizes locally sourced limestone and brine. After that, sodium carbonate is transformed to sodium bicarbonate via the carefully controlled process of carbonation. Through controlling this supply chain, Tata guarantees purity and efficiency in cost.
However, what makes Tata different from other companies is its capacity to differentiate the market and design products to meet specific needs. Medikarbâ„¢ is a product that Tata introduced in India as the nation’s first pharmaceutical-grade sodium bicarbonate that was branded and produced using GMP-compliant methods. This ensured consistency, sterility, and batch traceability–factors critical for medical applications such as dialysis or injectable use.
In Europe, Tata’s EcoKarb has been featured in global news because it was one of the first bicarbonate products that are low-carbon. In capturing CO2 in flue gasses and using it to make the product, the company has dramatically reduced its carbon footprint while achieving environmental goals and making the product a green alternative on the global market.
These breakthroughs illustrate that the production of sodium bicarbonate is not just about chemistry, but also about the evolution of business models as well as brand value, and globally positioning.

Understanding the Manufacturing Process
At the core, sodium bicarbonate production starts with soda Ash (sodium carbonate). The raw material is then reacted to carbon dioxide using an aqueous solution under controlled conditions. The chemical reaction occurs like this:
Na₂CO₃ + CO₂ + H₂O → 2 NaHCO₃
The reaction happens in carbonation towers, which are large vertical reactors in which soda ash dissolves in water, and COâ‚‚ gas bubbles into the liquid. The sodium bicarbonate that is formed is soluble only in small amounts and it starts to separate from the liquid as crystals that are fine.
The crystals then are:
- Filtrated and centrifuged to remove the solid from the liquid
- Washed to eliminate any impurities that remain or mother liquor
- Dryed using the hot-air dryer or vacuum dryers, based on the desired particle size
- Sorted and packed according to specifications for the product (pharma, food, industrial)
In the case of pharmaceutical production the process is given the rigors of pharmaceutical production. Air handling systems need to be HEPA-filtered. Surfaces need to be made of stainless steel, and simple to clean, and the batch record are required for each stage. Temperature, humidity and the control of contamination are all essential.
In carbon capture-based systems like in Tata Chemicals Europe, the COâ‚‚ is extracted from exhaust of boilers and other equipment used in process with amine-based or cryogenic capture techniques. This allows the same gas to be reused in production while significantly reducing emissions–demonstrating a win-win for business and the environment.
Market Scope and Profit Drivers
As straightforward as sodium bicarbonate may appear, it’s a major player in multi-billion-dollar markets across the globe. What makes it so popular with entrepreneurs is the fact that it doesn’t have a cyclical demand. This isn’t a luxury item that is out of fashion. It’s a key component in many vital services.
The most significant demand is derived from:
- Pharmaceuticals – Particularly for dialysis, injectable formulas, as well as antacids
- Food and Beverages – As leavening agent, pH stabilizer
- Water Treatment – Neutralizing the acidic waters and changing the pH
- Flue Gas Treatment – Capturing pollutants from industrial chimneys
- Fire Suppression – The primary element in the dry chemicals used to extinguish fires
- Animal Nutrition – Used in feed for livestock and poultry to regulate electrolyte balance
What’s interesting is the variety in packaging and quality of the product. A manufacturer can offer:
- Bulk sodium bicarbonate used in industrial uses (lower margins, more volume)
- Fine, food-grade bicarbonate suitable for bakery industry (mid margin)
- Bicarbonate USP/BP-compliant for pharma grade (high margin and low volume)
- Specialized carbon capture-based bicarbonate for sustainability-focused markets (premium pricing)
In India where the water treatment and pharma industries are growing rapidly producers can get an important market share with the proper certifications.

India is still importing a small portion of its sodium bicarbonate, particularly in the high-purity sector that gives local manufacturers an edge in terms of speed as well as customization and cost-efficiency.
Lessons from Tata: Building More Than a Factory
The development of Tata Chemicals’ bicarbonate portfolio wasn’t just about technological advancements or process efficiency. It was about establishing long-term trust and a clear vision. Under the leadership of industrial giant Ratan Tata the company was centered on quality, sustainability, and its people.
Important lessons to learn for those who want to become entrepreneurs:
- Consider margins beyond the surface: Tata invested in GMP facilities and carbon capture when it wasn’t a quick return. Now they are able to command premium prices and international focus.
- Create brands, not just products: Naming and segmentation (EcoKarb®, Medikarb™) has helped Tata transform from a commodity into a brand. Entrepreneurs should be thinking about doing the same, even for B2B.
- Respect the environment: Tata’s zero-liquid-discharge, COâ‚‚ reuse, and community engagement made their plant a benchmark. New entrepreneurs can gain quicker approvals and gain customer trust through the same practices.
- Automate earlier: Efficiency can’t increase based on the amount of manpower. Tata’s early adopting of Digital Twin and predictive monitoring ensured steady, reliable output.
This philosophy of slow, purpose-driven scaling is why the Tata model is worthwhile to study and replicate.
